NPACKING AND

NSPECTION
Your QSR synthesizer module was packed carefully at the factory. The shipping
carton was designed to protect the unit during shipping. Please retain this container
in the highly unlikely event that you need to return the QSR for servicing.
The shipping carton should contain the following items:
•
QSR with the same serial number as shown on shipping carton
•
AC Power Supply
•
Computer CD-ROM containing software
•
This instruction manual, plus lists of Mixes and Programs, and Quick Start guide
•
Alesis warranty card
It is important to register your purchase; if you have not already filled out your warranty
card and mailed it back to Alesis, please take the time to do so now.

OOKUP
The QSR works with the voltage of the country it is shipped to (either 110 or 220V, 50
or 60 Hz), and comes with a line cord or power supply suitable for the destination to
which the keyboard is shipped. With the QSR off, plug the small end of the power
adapter cordinto the QSR’s [POWER] socket and the male (plug) end into a source of
AC power. It’s good practice to not turn the QSR on until all other cables are hooked
up.
Alesis cannot be responsible for problems caused by using the QSR or any associated
equipment with improper AC wiring.

ROTECTORS
Although the QSR is designed to tolerate typical voltage variations, in today’s world
the voltage coming from the AC line may contain spikes or transients that can
possibly stress your gear and, over time, cause a failure. There are three main ways
to protect against this, listed in ascending order of cost and complexity:
•
Line spike/surge protectors. Relatively inexpensive, these are designed to
protect against strong surges and spikes, acting somewhat like fuses in that they
need to be replaced if they’ve been hit by an extremely strong spike.
•
Line filters. These generally combine spike/surge protection with filters that
remove some line noise (dimmer hash, transients from other appliances, etc.).
•
Uninterruptible power supply (UPS). This is the most sophisticated option. A
UPS provides power even if the AC power line fails completely. Intended for
computer applications, a UPS allows you to complete an orderly shutdown of a
computer system in the event of a power outage, and the isolation it provides
from the power line minimizes all forms of interference—spikes, noise, etc.
